Answer: option D
Step-by-step explanation:
The formulae for standard error = standard deviation/√n
But population standard deviation = 1.8 and sample size = n = 81
Standard error = 1.8/√81 = 1.8/9 = 0.2
Answer:
They would get 12oz of soup
Step-by-step explanation:
First, you would do 16x6 because you want to find the total amount of soup you have.
Next, after finding how much you have in total 96oz you then divide by how many people in this case is 8 then you get your answer.
10² ,+ 14² = 26²?
100+ 196 = 676?
they do not meet the Pythagorean criterion a² + b²=c so they are not a triple

Answer:
x=7, y=-9
Step-by-step explanation:
-9x – 9y = 18
-9x - 5y = -18
Multiply the second equation by -1
9x + 5y = 18
Add this to the first equation to eliminate x
-9x – 9y = 18
9x + 5y = 18
---------------------------
-4y =36
Divide each side by -4
-4y/4 = 36/-4
y = -9
Now find x
-9x -9y = 18
-9(x) -9(-9) = 18
-9x +81 = 18
Subtract 81 from each side
-9x +81-81 =18-81
-9x =-63
Divide each side by -9
-9x/-9 = -63/-9
x=7
